WEIGHING' AND COUNTING SCALE.

Application filed September 23, 1920. Serial No. 412,189;

To all whom itmcy concern:

Be it known that I; HENRY \VQSmEs, a citizen .of the United States,residing at Dayton, in the county of Montgomery and State of Ohi haveinvented certain new a 1 useful Improvements in \Veighing and C huntingScales, of which the following is a specification.

This invention relates 'to certain new and useful improvements inautomatic Weighing and counting scales of a type which is adapted tocount a plurality of articles of uniform weight by using one or more ofthe articles as a uni One object of the invention is to provide a scaleof the aboi e type which is accurate, simple in construction andefficient in operation and possesses the features hereinafter describedin connection with the accompanying drawings. 1

A further object of the invention to pivotally mount the unit receptacleon a pendulumgin such a manner that the load will always h e-supportedat exactly the same point andit'here will be no variation in theeffective length of the pendulum as the latter moves about its axis.Other objects of the invention wvill appear as the device is describedin detail.

The drawing illustrates a front elevation of a scale as constructed inaccordance with my invention. 1

Referring more particularly to the said drawing, .'1- represents aplatform or ta ble which; in the present instance, is supported onbrackets '-2 butniay be provided with any other well known support.Extending from the lower side of the said platform"1- are projections 3prov understood that said pivot'may be connect-' 'vided with openings--1 which receive the'fulcrum -5- of a scale beam -6.' v The beam -6 isprovided with a pivot -7 from which hangs a scoup 8'- in which thearticles-to be weighed or'counted are placed. The pivot 7- supports ascoop in the present instance, but it is to be ed with a platform or anyother receptacle well known in the art of scales. The beam 6-- is alsoprovided with a pivot 22 similar tothe p'ivot 7- and on the oppositeside of the fulcrum '5. The pivot '-22 supports a scoop -9- whoseprimary objectis to balance the scale but which "may be used for reverseweighing. When the articles'to be Weighed or counted are articles in thescoop 8.

placed in the scoop 8-, the end10 of the long arm of the beam isdepressed to an extent commensurate with the weight of the This variabledepression is secured by a pendulum-41+, the effective weight of which,when using the scale as a counter. consists of a unit formed of-one. ormore than one of the articles to be counted. When thescale is used forascertaining weight, a suitable unit weight is provided. The unit abox ereferred to is receivable by a receptacle or cup 12 supported by a yoke13 from a frictionless pivot '1-1 on the lower end of the pendulum. Thelength of the pendulum -11 is adjustableby a threaded sleeve 15-- in thepresent instance. The said pendulum extends downwardly from a hub .16supported from the platform 1 by a yoke -17 which receives a pivot 1bmounted in the hub. The hub --16 is connected to the end -10 of'the beamby a cam --19- and a steel tape-20. \Vhen the end -10 of the beam isdepressed, the cup l2- and the unit therein will swing upwardcommensurate with the amount of depression of the end --10 of the beamand. the quantity of articles in the. scoop 8. To permit the movement ofthe pendulum to be uniform for uniform variations in the quantity orweight of the articles in the scoop 8, the cam '-19 is provided. The cam19 permits the beam to exert a greater leverage the higher the pendulumis swung from a normal position which position it is in when plumb withthe pivot -18. p The unit receptacle 12 is pivotally connected with thependulum by means of a knife edged pivot which is so arranged that inall positions of the pendulum the weight of the receptacle willbe'supported thereon at exactly the same Cpoint. In the present instancethe knife e ged pivot is carried by the pendulum and isarranged at anangle at approximately 45 to the plumb line of the pendulum. This knifepivot extends into an opening, in the yoke 13 of the receptacle, of adiameter such that the yoke will swing freely on the knife edge of thepivot in all positions of the pendulum. Consequently, if the pendulumswings to the left,

along the dotted line, the point of support of the unit receptacle onthe pendulum will remainunchanged and the efiective length of thependulum will not be taining the weight. 27- are .cahbratcd forlquantlty and he t e cl pendulum.

pletely avoid the length of the pendulum which. the ordinary pivotbearing, such as the cylindrical pivot pin, with which the point o'lisupport of the receptacle continually shifts, as the pendulum moresupwardly, from a point at the top of the cylindrical pivot to a point atone side thereof, thereby gradually increasing the efiective length 0'?the pendulum and rendering the computation more or less inaccurate. l lith the knife edged pivot arranged as above described the unitreceptacle is always supported on an axis spaced an exact distance fromthe axis ot'gthe pendulum itsel'l also preferably mounted on a knifeedged pivot which, as shown at 18, is arranged at an angle to theopening in the yokeli, which opening is of a large diameter, so that theedge of the pirot ot the pendulum will, always be supported at exactlythe same point on the bearing of the yoke. To absorb vibrations, thebeam 6 is provided with a dash-pot -2l as is usual in pendulum balancescales. To indicate the extent of depression of the end -10 of the beam,whereby the weight or quantity of the articles in the scoop -Q isascertained, the hub -16-- is prov1c with a pointer -23'- having anindex thread 24 movable over the face of a segmental dial 25- mounted onthe platform l The dial .is provided with a plurality of calibratedlines, the upper one of which is calibrated for pounds and 1s used whenthe is employed. in ascer- The remaining hues in alignment with numberson the pointer in the present instance which indicate the number ofarticles comprising the unit in the cup --12-'. In the present instancethe dial is calibrated "for units consisting of one, fire, ten and ahundred articles. l l hen the s'alc is in use and it is desired toascertain in the number of pieces of uniform weight, either one, live,ten or a hundred of said articles are deposited in the cup --12- to forma unit while the articles to "be counted are placed in the scoop. Thenumber of the articles may then be read from the lines -27- and thepointer '2c in addition to the scoop -9 and the pendulum -ll of variablelength, the scale may be T he pendulum' s hcre shown, the weights a ofnuts, mounted on. threaded studs carried by the. hub of the pendulum,but obviously they may be of ai'iysuitable character. The beam may bealso provided with an adjustable weight and, as here shown, the beam hasa calil'a'ated portion 30 on which is slid- ;ably mounted a weight 31ot' a well known type. By means of this adjustable weight l am able towei 'h the. load in the receptacle 8 when the indicator shows a desirednumber of articles without removing the articles from the unitreceptacle. Moreo cr. when the indicator has reached the limit of itsmovement the scale may be caused to rt peat by adjusting the weight onthe beam until the indicator again assumes its-zero position, afterwhich additional articles may be placed in the receptacle andthe iud''ator will indicate the number of said articles in the same manner itwould upon the first operation. it will be noted that after a number ofarticles in the scoop 8- have been counted by wcightt-he same number maybe counted in thc sc oop 9- thereby brindin the index back to zero.
